Provided is a combination agent that combines N-[(1S)-2,2,5,7-tetrafluoro-2,3-dihydro-1H-inden-1-yl]sulfamide with an AMPA-type glutamate receptor antagonist such as 3-(2-cyanophenyl)-5-(2-pyridyl)-1-phenyl-1,2-dihydropyridin-2-one or 2-fluoro-6-(3-fluoro-8-oxo-7-(pyridin-3-yl)-7,8-dihydro-6H-pyrano[3,2-b:5,4-b']dipyridin-9-yl)benzonitrile, and it has potential for use as a therapeutic agent for epilepsy.

Epilepsy treatment agent

The present invention is directed to a method of treating pain comprising the administering the following 1-indansulfamide compounds: N-[(1S)-2,2,5,7-tetrafluoro-2,3-dihydro-1H-inden-1-yl]sulfamide, (&#x2212;)-N-(7-chloro-2,2,5-trifluoro-2,3-dihydro-1H-inden-1-yl)sulfamide, N-[(1S)-2,2-difluoro-7-methyl-2,3-dihydro-1H-inden-1-yl]sulfamide, and N-[(1S)-2,2,5-trifluoro-7-methyl-2,3-dihydro-1H-inden-1-yl]sulfamide.

Therapeutic and/or preventive agent comprising 1-indansulfamide derivative for pain

Novel indansulfamide derivatives or a pharmaceutically acceptable salt thereof such as N-[(1S)-2,2,5,7-tetrafluoro-2,3-dihydro-1H-inden-1-yl]sulfamide, N-[(1S)-2,2,4,7-tetrafluoro-2,3-dihydro-1H-inden-1-yl]sulfamide, (+)-N-(2,2,4,6,7-pentafluoro-2,3-dihydro-1H-inden-1-yl)sulfamide, have an action of improving Seizure Severity Index (Score) in mice kindling model. Thus the compounds or the salt thereof are expected as a drug for treating epilepsy.
